    <p>I'm attempting to cross compile the perl interpreter for an ARM architecture (<a href="http://www.friendlyarm.net/products/mini2440?lang=en" rel="noreferrer">FriendlyARM Micro2440</a>). I'm using the <a href="http://www.friendlyarm.net/downloads" rel="noreferrer">ARM-Linux GCC 4.4.3</a> cross-compiler provided by the manufacturer. The board is running Linux 2.6.</p> <p>I was able to cross-compile a basic "Hello World" application successfully, and it ran on the target machine.</p> <p>I've downloaded the perl v5.12.3 source. I was able to do a normal compilation of perl for Ubuntu. I'm now attempting to do a cross-compilation for the ARM board. I'm working out of the perl-5.12.3/Cross folder in the source download.</p> <p><code>make patch</code> succeeded, but when I run <code>make perl</code> it fails with this</p> <pre><code>LD_LIBRARY_PATH=/home/reed022/.local/share/Trash/files/perl-5.2.12.3 arm-linux-gcc -o miniperl \ gv.o toke.o perly.o pad.o regcomp.o dump.o util.o mg.o reentr.o mro.o hv.o av.o run.o pp_hot.o sv.o pp.o scope.o pp_ctl.o pp_sys.o doop.o doio.o regexec.o utf8.o taint.o deb.o universal.o globals.o perlio.o perlapi.o numeric.o mathoms.o locale.o pp_pack.o pp_sort.o \ miniperlmain.o opmini.o perlmini.o -lnsl -ldl -lm -lcrypt -lutil -lc LD_LIBRARY_PATH=/home/reed022/.local/share/Trash/files/perl-5.2.12.3 ./miniperl -w -Ilib -MExporter -e '&lt;?&gt;' || make minitest ./miniperl: 1: Syntax error: word unexpected (expecting ")") </code></pre> <p>I think the relevant part of the output is the <code>./miniperl -w -Ilib -MExporter -e '&lt;?&gt;' || make minitest</code> part. Though I'm not sure. It seems confusing to me that the cross-compilation environment would try to run tests, since it's targeting a different system than the one it's being built on.</p> <p>I'm completely lost as where to go from here. The people I've talked to haven't had much experience with cross-compiling programs.</p> <p>UPDATE<br> I decided to delete the perl source folder and re-extract it, thinking that the previous compilation of perl for the Ubuntu host machine might have been messing with the current cross-compilation. I'm now getting a different but similar error.</p> <pre><code>`sh cflags "optimize='-O2'" generate_uudmap.o` -fexpensive-optimizations -fomit-frame-pointer -O2 -march=armv4 -mtune=strongarm1100 generate_uudmap.c CCCMD = arm-linux-gcc -DPERL_CORE -c -fexpensive-optimizations -fomit-frame-pointer -O2 -march=armv4 -mtune=strongarm1100 -O2 -Wall arm-linux-gcc -o generate_uudmap generate_uudmap.o -lnsl -ldl -lm -lcrypt -lutil -lc ./generate_uudmap uudmap.h bitcount.h ./generate_uudmap: 1: Syntax error: word unexpected (expecting ")") make[1]: *** [bitcount.h] Error 2 make[1]: Leaving directory `/home/reed022/Downloads/perl-5.12.3' make[1]: Entering directory `/home/reed022/Downloads/perl-5.12.3' make[1]: *** No rule to make target `more'.

    1. CONever did this successfully, but you might want to check out the OpenEmbedded project. They provide a build framework for creating embedded Linux distros. http://wiki.openembedded.net/index.php/Main_Page

    2. COThe makefile is clearly trying to run your ARM binaries on your (Intel?) build machine. (I guess that the magic number does not match any known executable file type, so the shell tries to run it as a shell script and gives the weird error you see). There must be something wrong with your cross compilation setup.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
